Calibration
7. Check +12 Volt output at J2-8. Output should measure between +11.4 and +13.2 Volts. Output is not adjustable. Replace
PS1 if output is not within this range under normal load conditions (<2.5 Amps).
8. Check -15 Volt output at J2-11. Output should measure between -14.55 and -15.45 Volts. Output is not adjustable. Replace
PS1 if output is not within this range under normal load conditions (<1.2 Amps).
9. Check +15 Volt output at J2-4. Output should measure between +14.7 and 15.3 Volts. Output is not adjustable. Replace PS1
if output is not within this range under normal load conditions (<2.5 Amps).
Note: If one or more DC outputs do not meet specifications, replace PS1.
Multi-Output Power Supply PS2
Calibration of Power Supply PS2 consists of checking each output for proper voltage under load, and making adjustments when
necessary. Calibrate the supply when you replace it, and semiannually as described in the periodic maintenance procedures
WARNING: Dangerous AC voltages are present on connectors P1, P2, and P3 of Power Supply
PS2 during the following calibration procedure.
CAUTION: Be careful when making the following measurements. Short circuiting a DC output can cause burns
and equipment damage.
Note: Make sure PS2 is fully installed with all loads connected before performing the following calibration procedure.
Calibrate DC Power Supply PS2 as follows:
1. Remove Left Side Cover.
2. Remove Component Tray Cover.
3. Make sure Workstation’s AC power plug is connected to facility’s AC outlet.
4. Turn Workstation on and allow system to boot.
5. Make sure that LEDs DS1, DS2, DS3, DS4, and DS5 are all lit.
